What organelle carries out photosynthesis?


Quick Answer

The organelle that carries out photosynthesis is the chloroplast. It contains chlorophyll, the green substance in plants that allows them to create food from carbon dioxide and water.

The most vital characteristic of plants, as well as what makes them unique, is their ability to manufacture their own food by the process of photosynthesis, according to Florida State University. Photosynthesis harnesses light energy and transforms it into chemical energy in the form of sugar molecules that plant cells use for fuel. Organelles called chloroplasts carry out the process of photosynthesis.

Chloroplasts are specialized cellular parts that are analogous to organs in the body. The structures contain a lipid called chlorophyll, which is the substance that gives plants their green color. Chlorophyll captures light from the sun made up of photon particles. The start of the process of energy transformation occurs when photons collide with the electrons in the chlorophyll molecules.

Water and carbon dioxide from the air combine, and the process rearranges their atoms to create a sugar molecule. Within the sugar molecule are bonds that store energy from light. A by-product of this process is oxygen that comes from water. The entire process takes place in the chloroplast, as described by Houston Community College.
